Changing the technology for handling freight locomotives at the Eastern Polygon

Abstract

One of the main tasks of the Russian Railways company is to attract customers to railway transport by various methods. The important requirements of customers today include, among other things: the formation of routes; reduction of delivery time; timely removal of the declared volume of cargo. To meet these requirements, the technology of driving heavy-weight and connected trains is used on the roads of the Eastern Polygon under conditions of updating the locomotive fleet. In 2016, the first delivery of new 3ES5K locomotives was made to the Eastern Polygon. Thanks to the applied landfill technologies for handling locomotives and the use of 3ES5K series electric locomotives, the formation of trains weighing 7 100 tons was organized. The East Siberian Railway is part of the Eastern Polygon, and electric locomotives and diesel locomotives of various series are used in its boundaries in the freight traffic to ensure the export, admission, reception and departure of wagon traffic. Locomotives are handled according to the accepted technology at the Eastern Polygon, taking into account minimal downtime at technical stations for both locomotive and locomotive crew changes. Today, the capacity of freight traffic allows to form up to ten trains weighing 7 100 tons per day. However, due to the insufficient number of powerful locomotives, they are still formed weighing 6 000–6 300 tons, which leads to an increase in threads in the regulatory schedule. Under conditions of limited capacity of stations and sections, further updating of the fleet of freight locomotives is extremely urgent. The scientific article examines the organization of traction services at the Eastern landfill, in particular within the boundaries of the East Siberian Railway, during the transition to the 3ES5K series of locomotives with axial control.
